I was given a M-max box with my stock MC21 but with no instructions. I just did the 1st wire splice with the orange/blue wire but wasn't sure if the M-max would do the 2nd GPS wire splice trick for me. If I just plugged it in between the GPS connectors and left all the other wires/connectors on the M-max alone, would this accomplish the gps splice for me?

Thanks!

here are a couple of diagrams on the M-Max box.

Hopefully this will clear up your questions.

Thanks! So I guess it doesn't do anything for my gps wiring... Time to yank it and do a proper splice.
